Answer:
I think the answer is y=23x+3....
Sorry if I get it wrong! Have a nice day! (:
Sin 30= x/8
X= sin 30*8
X=4
If the price went down $5 per day for four days straight, then it would have went down $20 total after the four days.
Answer:
The ratio is 10 : 1, or 10 to 1
Step-by-step explanation:
Answer:
slope = 2
Step-by-step explanation:
Find 2 points on the line that land perfectly on the grid. I'll choose these 2 here:
(-2, -1) and (0, 3)
Rise is the change in the y value from one point to the other, and run is the change in the x. Looking at these 2 points, y went from -1 to 3. That is a <em>rise</em> of 4. The x went from -2 to 0, so that is a <em>run</em> of 2. "rise over run" means rise literally over run in a fraction like this:

The more proper way to calculate slope looks like this, but it's really the same thing in the end:

where (x1, y1) and (x2, y2) are your 2 points.
Finally, the slope of this line is:

That's a rise of 4 over a run of 2, and that simplifies to just a slope of 2.
